Hitman, I have the HD ones and kinda wish I had the comfort ones. When you go over bumps and lane dividers with the HDs it thuds and rides pretty rough. Even with the HD's these cars won't be the best handlers, you need to do a lot more than shock absorbers to get any "performance" out of the suspension. Im not saying these are bad handling cars, you can pretty much feel everything through the steering and oversteer is pretty predictable but there can be a lot of slop after 20 years.

I bet a good set of stiff high speed rated tires would do more than the difference between the comfort and HD.
